What you say is trange:
it used to boot with the current qemu configuration. As PREP is not
supposed to use the open-firmware interface, it does not care about
seing or not the PCI host bridge in the tree.
So, imho, it would be a good choice not to make a change into qemu until
we get a new stable OHW BIOS.
